i herd it in church one morning and thought it could use a bassline
riff one-play twice
G|-4-2-0-----0-----|
D|-------2-4---4-2-|
A|-----------------|
E|-----------------|
riff two- play after riff one
G|0-0-2-2-4-4-7-5-4-2-4-2-0--------0-0-0---0--0--|
D|-------------------------4-2-4s7-------0--4----|
A|-----------------------------------------------|
E|-----------------------------------------------|
if you want to play it in a lower octave, tune the E string to D
